ok, i have a skoda symphony stereo with full FIS from a VW Golf mk4.It uses can bus for displaying data on top part of screenI am using arduino to find the canbus message ids from stereo to cluster and cluster to stereo. I want to display other paramenter(eg boost, speed, etc) on the FIS screen. any ideas?

Hello. I also tried the new code on Dccduino clone with 12 Mhz quartz but it didn't work on FullFIS from Passat B5 FL. Do you have any ideas why it's not working? Messages from OEM radio works well. Thanks for any reply ;)

change lines:String FIS_WRITE_line1="FIS protocol emulator by kovo"; //upper line 8characters are static, more then 8 will rotateString FIS_WRITE_line2="http://kovo-blog.blogspot.sk"; //lover line 8characters are static, more then 8 will rotate

I already have an A3´02 cluster and I tried to write in the cluster with your original code but it doesnt work... only bulbs, brake pad, washer fluid advise, maybe the cluster dont show radio message when have this troubles??

Maybe is can bus, but I found electric diagram from ´96 to ´03 A3 8l and only navigation plus use can bus system, all "standar" radios use 3 line ENA/DATA/CLK, maybe is not active in coding of the cluster I try to check that.

appear in different character. I changed the two line text and 123456789 is ok, the big letters ABCDEFGH... also works. the problem caused by the small letters abcdefgh.. when I used any small letter different character appear on the FIS. Any idea how can I write small letter what I want to the FIS?

Cluster can not display small characters, i forgot to commit upper case version with strings. Check my youtube videos about know characters by cluster, i made loop wich try to write character with ascii table numbering from zero to 255

Its ok, the small to big conversion is working, but there some other problem. The first line begin to scroll under 8 character also but the second line is fine I dont know why is it. The other is refres or something I think because the background light of the two line go off for a sec.

ok, and coding of cluster is ? http://www.ross-tech.com/vag-com/cars/vwmkIV.html17-Instruments: K1 -- KWP-1281 Look at the first two digits in the coding. Add the values for the options together to get the correct coding.

so thats the problem probably, on audi at least for this type of communication (radio only, no navi) cluster must be coded without 16 try it please if you can. at least just to be sure, I use all kind of arduino, clones original it work on all

Were you able to set up a test bench with a dismounted gauge cluster? I have an Audi cluster sitting on my desk but the FIS display shows a lot of warnings. Is there a trick to hooking it up? It would be easier to work with that rather than sitting in the car:)

of corse you can, i'm on vacation so for now just link: http://www.audizine.com/forum/showthread.php/405961-Understanding-differences-between-Audi-A4-clusters-and-the-compatibility-issues you need to ground problematic parts like abs, brake pads wear sensors etc ... for fuel you need to put resistor between pin and ground, value must be search online ... (audi a4 b5 its 47ohm, a6 470ohms...)

Hi, you mention to use pull up resistor. Can you provide a schematic how to connect the Arduino to radio (with resistors) and the LCD display. I have an even older GAMMA BOSE with 3 line protocol. Would like to try if that works too...
